Constantin Fahlberg (*22 December 1850 in Tambov, (Russia); † 15th of August 1910 in Nassau) (Germany)) discovered the sweet taste of anhydroorthosulphaminebenzoic acid in 1877/78 when analysing the chemical compounds in coal tar at Johns Hopkins University for Professor Ira Remsen (1846–1927). Later Fahlberg gave this chemical "body" the trade name Saccharin.
